DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The aforementioned illustrations and following detailed descriptions are exemplary for the purpose of further explaining the scope of the present invention. Other objectives and advantages related to the present invention will be illustrated in the subsequent descriptions and appended tables.

FIG. 1 is a schematic view of an appearance of a coil assembly according to the invention. As shown, the coil assembly according to the invention includes at least one coil unit 1, a plurality of odd distributing pipes 2 and a plurality of even distributing pipes 3.

The coil unit 1 includes a plurality of odd coils 11 and even coils 12 configured in a horizontal manner. Each of the odd coils 11 stacks over each of the even coils 12 in stagger. All of the odd coils 11 and the even coils 12 are made of stainless steel or galvanized steel, and can be subject to surface treatment by brushing or embossing.

Each of the odd distributing pipes 2 respectively communicates with both ends of each of the odd coils 11.

Each of the even distributing pipes 3 respectively communicates with both ends of each of the even coils 12. Thereby the above-mentioned configuration constitutes a new coil assembly.

FIG. 2 is a schematic front view of a coil assembly after being oriented according to the invention. FIG. 3 is a schematic top view of a coil assembly after being oriented according to the invention. FIG. 4 is a schematic side view of a coil assembly after being oriented according to the invention. As shown, when the invention is put into practice, the plurality of coil units 1, the plurality of odd coils 2, the plurality of even coils 3, a frame 4, a first distributing pipe 5 and a second distributing pipe 6 are carried and oriented in site. Each of the coil units 1 combines to the frame 4 in stack. The frame 4 includes a plurality of straight rods 41, a plurality of crossbars 42, a plurality of triangle connecting studs 43 connecting the straight rods 41 to the crossbars 42, a tetragonal connecting studs 44 connecting the straight rods 41 to the crossbars 42, a pentagonal connecting studs 45 connecting the straight rods 41 to the crossbars 42, and a plurality of spacers 46 each of which locates between one odd coil 11 and one neighboring even coil 12. The odd coil 11 inlet and the even coil 12 inlet respectively couple to the first distributing pipe 5. The odd coil 11 outlet and the even coil 12 outlet respectively couple to the second distributing pipe 6 which are of U-shaped tubular body. Each side of the frame 4 combines with a closing plate 47. A top of the frame 4 combines with a top lid 48 having a plurality of through holes 481. A bottom of the frame 4 combines with a bottom plate 49 for the application to a condenser or ice storage device in order to reach the effect of easy handling and easy assembling.

When in use, a working fluid (typically brine) flows through the odd coils 11 and the even coils 12 configured in horizontal manner. The orientation of the odd distributing pipes 2, the even distributing pipes 3, the first distributing pipe 5 and the second distributing pipe 6 allows the working fluid to pass forward in one path so as to reach the equal distribution effect. Furthermore, the top lid 47 having the plurality of through holes 471 can prevent any broken ices float away from coil units, of broken ices formed after melting, achieving effective refrigerating effect.
